Title: Detecting method of wear of hydraulic machine due to earth and sand
Inventor: TOSHIMA MASAMI
IPC: G01B13/00
Filed: 1987-10-09
Abstract: PURPOSE:To know the amount of wear due to earth and sand without breaking down an apparatus and to estimate the time of overhaul, by a method wherein a plurality of space parts formed by changing the thickness of a partition wall are arranged at the back of the outer periphery of the surrounding wall of a channel. CONSTITUTION:A plurality of space parts 5 formed by changing the thickness of a partition wall (h) are arranged in the whole periphery of a seal surface 3 of a facing plate 2 facing a runner 1 of a hydraulic turbine, and a detector 14 and a compressor 15 are connected to these parts. The thickness (h) of the partition wall is set to be 3-4mm at the minimum and about 10mm at the maximum, and the pressure in the space parts 5 is made somewhat higher than the internal pressure of a channel part by compressed air. When the wear 12 of the seal surface 3 occurs due to earth and sand during an operation, the channel part turns to communicate with the space part 5 and the compressed air blows into the channel. After this blow is detected by the detector 14, a valve 13 is closed, and other space parts 5 are dealt with in the same way. Accordingly, the amount of the wear due to the earth and sand is known easily and the time of overhaul can be estimated.

Title: Charge transfer device
Inventor: YAMAMOTO TOSHIRO
IPC: H04N5/335
Filed: 1985-11-13
Abstract: PURPOSE:To set a dynamic range within an optimum range, and to improve a signal-to-noise ratio when the quantity of charges to be transferred are little by transferring charges, selecting the unit number of a charge transfer element in response to the quantity of charges stored in a charge storage region. CONSTITUTION:The plural units of charge transfer devices are disposed to one charge storage region 30 through the combination of transfer gates 4a1, 4a2 operating mutually independently and CCD units 5a1, 5a2. Unit number transferring the charges of the charge transfer devices is selected in response to the quantity of charges stored in the charge storage region 3a. A semiconductor material having an energy band gap fitted for an aimed wavelength zone is used as photoelectric conversion elements 1a, 1b... arranged in each picture element region. Accordingly, the dynamic range of the device can be set within an optimum range, and fixed-pattern noises are detected as outputs corresponding to units inputting no charge when the quantity of charges to be transferred is small, thus improving a signal-to-noise ratio by correction arithmetic operation.

Title: Picture data compressing method
Inventor: YONEKAWA HISASHI
IPC: H04N19/136
Filed: 1986-10-28
Abstract: PURPOSE:To improve qualities of reproduced pictures, by setting maximum quantizing errors of components to be encoded other than DC components at levels which are equal to or lower than the double of the standard deviation value of each component and/or setting maximum quantizing errors of appropriate components other than the DC components at levels which are equal to the half of the standard deviation value of each appropriate component. CONSTITUTION:Since the lowest frequency components except DC components of transformational coefficient matrices obtained when block pictures are orthogonally transformed are the most influential to the appearance of block boundaries of a reproduced picture, quantizing error widths of the components are set at levels which are equal to or lower than the half of the standard deviation value of each component. Moreover, since high-frequency components are most influential to the appearance of a crepy artificial pattern which appears in a picture edge section having a large density difference, quantizing error widths of all components except DC components are set at levels which are equal to or lower than the double of the standard deviation value of each component. Therefore, block boundaries and crepy artificial patterns hardly seen in a reproduced picture and excellent picture data compression can be realized.

Title: Pouring method
Inventor: HAYASHI MASANORI
IPC: B22D27/00
Filed: 1985-11-15
Abstract: PURPOSE:To permit pressurized pouring to a green sand mold and to obtain a product having good quality without shrinkage cavities, etc. by pouring a molten metal into a casting mold in the amt. smaller by as much as the molten metal for a sprue part, then inserting a packing plug into the sprue. CONSTITUTION:The molten metal is poured into the casting mold 12 in the amt. smaller by as much as the molten metal for the sprue part and thereafter the packing plug 19 is inserted into the sprue 21. A pressure is exerted to the pouring metal to some extent to accelerate the flowing in of the pouring and to permit the pressurized pouring into the green sand mold. Since the pressurized pouring into the green said mold is made possible, the pressurized molten metal is made to reach all the corners in the casting mold. The product having the good quality without having the shrinkage cavities, etc. is thus cast. The part of the sprue 21 where the plug 19 is inserted is not cast and therefore, the pouring is correspondingly economized and the product is cast at a good yield.

Title: Gate drive circuit
Inventor: ASHIZAKI YUKIHIRO
IPC: H02P7/29
Filed: 1988-10-11
Abstract: PURPOSE:To obtain a gate drive circuit with low cost by connecting the anode side of a Zener diode/connected in parallel with a capacitor, with the gate of a power MOSFET and connecting the cathode side thereof with a power source having ON/OFF function. CONSTITUTION:When LU=RL=Low level and RU=LL=High level signals are fed to transistors 18a to 18d, power MOSFET 15a to 15d are turned ON while power MOSFETs 15b, 15c are turned OFF. Consequently, current flows through a motor in the direction of an arrow. In order to sustain ON condition of the power MOSFET 15a, potential VB at point B must be higher by the gate threshold voltage VSH than the potential Vc at point C. Potential at point D is approximately ground potential while the potential VF at point F is the difference of the output voltage VH from a booster circuit divided by resistors 22b, 23b and the potential VZ of a Zener diode 19a, and thereby ON state of the power MOSFET 15d is sustained.

Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency in mixing the crushed garbage, etc., in a mixing structure having a container rotated around an inclined axis and provided with a blade on its inner periphery by forming an appropriate clearance with the inner edge of the blade and furnishing a columnar body at the axial center of the container. SOLUTION: A container with a blade 2 formed on its inner periphery and contg. a material M is rotated around an axis L, and the materials M are mixed not only in the direction orthogonal to the axis L but also in the direction of the axis L. Namely, when the container 1 is rotated, the material M flows in direction of the arrow (a) to pass above the lower end of the columnar body 3 in the range X and flows in direction of the arrow (b) in the range Y, and then the flow is blocked by the columnar body 3 to form a flow in direction of the arrow (c). The material M then flows in direction of the arrow (d) in the range Z. Consequently, the materials M are mixed not only unidirectionally but also two-dimensionally, and the mixing effect is improved.

Title: Rotary damper
Inventor: WAKABAYASHI TADAMASA
IPC: F16F9/14
Filed: 1992-08-31
Abstract: PURPOSE:To provide a rotary damper wherein large resistance force is generated even if it is small sized to absorb a shock at the final time of closing rotation against also an opening/closing cover in heavy weight of generating large rotary torque, because rotary action is delayed by moving a piston advanced/reversed while rotated in a hollow part. CONSTITUTION:When an opening/closing cover tends to further perform closing action from a condition at an almost 90 deg. rotary angle, since a valve member 8 already performs closing action, viscous liquid 9 in the first liquid chamber 4 tends to flow into the second liquid chamber 5 through a slight space 3f formed by a flat smooth surfaced external peripheral surface 3d in the vicinity of the point end part of a piston 3 and a flat smooth surfaced internal peripheral surface 2e in the vicinity of the bottom wall part of a main unit case 2. By dynamic pressure resistance and viscous resistance generated when the viscous liquid 9 passes through this space 3f of functioning as an orifice, moving the piston 3 advanced is delayed. As a result, the opening/closing cover, connecting a rotary shaft to a connecting member 7, is actuated to slowly close.
